Fanarts, Posters, Disk Art, Logos loading

I've just upgraded to Gotham and the respective Nox skin for it and all are working fine other than the fact its not imported any files/images at all even though they are all stored locally.

When i go to files it shows all my folders in there but clicking "edit source" for each item shows as "none" under "this directory contains"

I tried changing the "none" to the usual movies/tv show and it scanned it in as normal but the Poster quality is really poor even though i have the advancedsettings.xml changed keep a high resolution and it only picked up the poster and fanart when i have the logo, diskart, clearlogo and clearart pictures in there.

Any ideas on what i need to do for it to pick up the entire contents of my folders?
